The warning light doesn't tell you how healthy the battery is, it tells you if there are any problems with the charging system. A flickering light means charging is intermittant for some reason, so it would be worth checking the alternator or voltage regulator, which might be on the way out. It's worth also checking that the warning light circuit and bulb are ok - if it lights up brightly and continuously when you switch the ignition on, then goes off when you start the engine, it's ok. Hope that helps.

Why does my mercury villager make a loud noise when accelerating that stops when you take your foot off the pedal?

If this is a general noise, it could be the transaxle. When you are accelerating, the engine is pushing the gears, and when you let go of the pedal, the vehicle starts to shift back down. If this is an engine noise, it could be predetonation or a valve problem.

What are the effects of a loose ground cable in a Kia Sorento?

If the loose cable is the main one from the negative side of the battery, then everything will flicker simultaneously with the key on and the engine stopped. When the engine is running, the alternator will keep things energized. If you have a loose groung cable on one particular accessory, only that accessory will flicker or just remain off.

Why do the dash lights and headlights flicker on a 2000 Mercury Cougar?

There are several things it could be, but the most obvious and common is a bad battery. Most people incorrectly diagnose this as the alternator, however, it is in fact a bad battery. The battery is not holding a charge and is constantly placing a full drain on the alternator produing your flickering/pulsing. Check the voltage on the battery with the engine off immediately after running the engine for at least 15min. Wait a few hours (overnight even better) and check the voltage again. Anything more than a tenth of a volt drop or even really hundredths or so and you have a failing battery. For ex. right after running if the battery reads 12.5V and then after say 8-12+ hours if the battery reads 11.9V you definitely have a failing battery. If it does not seem to be a bad battery, repost and we'll go from there on less likely causes.
